I've lurked on this forum for many years, never felt like I had a weight-worthy question or comment. I got something I need some advice on.

For my CX alu tank, I'd like use a CF seatpost to dampen the ride (as well as reduce weight). 26.8mm diameter. Setback preferred.62kg rider.

Q1-Seatpost recommendations? Q2-Found an old Easton CT2. The seat clamp (alu) has unbonded from the post (carbon). Can't realistically take off the clamp, so I'm looking for a very low viscosity (ie, very liquid) carbon-metal adhesive to pour into the minimal space btwn clamp and post. Any recommendations?

If you race I'd get a Thomson Masterpiece (aluminum) post and just deal with it. If you don't race I have that seatpost you're trying to fix and it's been hassle free for over 10 years. If you can fix it great but I wouldn't race carbon unless you're a light and skilled rider.

26.8mm is a really strange size. If you were in need of a 27.2 or a 31.6 (maybe even 30.9 if this were the MTB forum) then you would have plenty of answers. It sucks to say it, but you may not be able to shave grams in this department. You could try a saddle with carbon rails to dampen your ride a little. There are of course many other factors that I'm sure you've already accounted for as far as ride quality is concerned but given the weird sizing, you may be SOL.

I´ve seen carbon posts breaking in CX and made some for a CX with mostly failures as result, in a CX size post they arent that long you get a very little weight gain with a Thomson post instead for a New Ultimate carbon and always worrying about breakage for the latter.
